When this challenge launched, the summer was fresh and green; as winter draws close, it's time to say farewell to memories of backyard barbecues and laying in the sun. So too, this is the last more...

I picked up a helper to move the engineering side along a little more quickly, so I finally have some time to post. As a total rookie, the learning curve to get the TI to bend to my will is pretty more...
